From our processes and quality controls to our steadfast integrity with U.S. and international regulations, we invest in our advanced in-house laboratories and third-party testing, as well as state-of-the-art equipment, giving us total control over our ingredients and formulas.
Every supplement we manufacture undergoes four rounds of testing to ensure every supplement meets our high standards. As soon as a raw material enters our facility, we test its identity and purity. Whether it’s mixing ingredients, testing a finished product before it’s shipped, or monitoring its shelf life, quality guides our every decision.
The best nutritional supplements begin with the best ingredients. Thorne’s formulas are built on a foundation of ingredients that are both clinically researched and sustainably sourced. To ensure the purity and potency of our ingredients, we implement a strict ingredient control system.
Every ingredient is quarantined until it meets specification for identification, concentration, and purity. As a result, every batch of Thorne’s supplements delivers optimal absorption, safety, and efficacy.
